SELF-CLOSING COCK.

SPECIFICATION forming part of Letters Patent No. 704,121, dated July 8,1902.

Application filed September 13,1901. Serial No. 75,246. (No model.) i

To all whom, it may concern Be it known that 1, PETER SOHWEGEL, acitizen of the United States, residing at Dayton, in the county ofMontgomery and State of Ohio, have invented certain new and use-.

tion of a cock that shall close automatically and have such form ofvalve that the closing .of the same shall be absolutely tight.

The mechanism is illustrated in the accompanying drawings, in whichFigure 1 is a side elevation with parts in transverse section to exhibitthe interior. Fig. 2 is a side view of the elastic part of the valve.

The letters and numerals designate like parts in the two views.

The body is cast of brass and comprises the main hollow body A, which issupported on a wall when in. use by the ears A A, which extend from therear portion of said body, the cone-shaped seat near the lower end, theextension G at a right angle to said body, and the inner bearing J. Thelower end 4 of the body and the end 5 of the extension are threaded toreceive the usual union-coupling. When the cock is exposed to the cold,the drainage-pipe I is attached to said extension. To the top of thebody is screwed the cap B, which is provided with the ears B tosupportone end of the lever E, the same resting on the top end of thevalve-stem C. To the outer end of this lever is joined the rod F, whichis lengthened to suit the conditions, and the top end is provided with asuitable handle. The cap is provided with the gland D to pack about thevalve-stem. The lever is provided with the recess 6 (indithe end of saidvalve-stem. The valve-stem- 0 extends from above the cap to near thebottom of the body. A portion of the upper part is threaded and whichthe adjusting-nut H traverses. To the lower end of this stem is securedthe metallic valve 1, with the rubber plug2 beneath. These have orificeswhich embrace the stem and are securely fastened by the nut 3. Theseparts comprise the valve and conform to the shape of the seat, therubber being slightly larger than the metallic part to make the closingsecure. The spiral spring t rests on the ledge J, bears up against thenut II, and thereby the valve is closed against its seat. The spiralspring 3 is held between this nut and the cap and serves to keep the nutin its position on the stem by adding to the friction of thescrew-engaging thread. If greater tension is required to carry the valvewith more force against its seat, the nut'is screwed down on the stemuntil the desired tension is attained. This nut is provided with lugsfor convenience in turning it.

In use a'pipe leading from the street-main is connected with the bottomof the cock and a discharge-pipe is attached to the lateral extension toconvey the water to the closet-bowl for flushing the same. To have thewater flow through the cook the lever must be depressed, and on itsbeing released the recoil of the spiral spring closes the valve.

What I claim is- In a self-closing cook the combination of the bodyhaving suitable infiuent and efiluent orifices, the bearing-ledge and aconeshaped seat, the closing-cap provided with ears and a packing-gland,the stem with its metallic and rubber rings forming the valve,

the threaded adj usting-nut held on said stem,

the spiral spring for closing said valve, the spiral spring for stayingsaid adjusting-nut, substantially as described.

In testimony that I claim the foregoing as my own I affix my signaturein presence'of two witnesses.

- PETER SOHWEGEL.
